I used short extensions on the front. For the rear, I have a 270degree extension that I bent for one tire and a short extension hose of the other on each dually. I got some stem stabilizers (really plastic plugs that I drilled for the extensions). I had to buy a large quantity of those plastic plugs to other them, but they work good.
